Assembly (G4220-60007) have a large pore size of about 20 m and filter
out particles before they reach the pump.
2 An outlet filter (average pore size 5 m; Outlet filter Quaternary
Pump/Flexible Pump (G4204-60004)) between pump head and pressure
sensor filters out particles which may be created in the pump by wear of
piston or wash seals.
This filter can be replaced as required.

pore size of about 0.3 m ( Inline Filter Assembly (5067-5407)).
